Apply Data structure to a flattened structure

Hey guys,

I was struggling with a flattened list of points, which originally belonged to a set of curves that i divided into equal lengths. For reasons i dont want to bother you with i had to flatten them, but later on i needed the original data structure back.

I searched online and i found some topics about this but not quite what i was searching, so i thought i'd post a question here. By the time i could start a discussion i already wrote the solution :D

So i thought i'd share it with you guys probably there are more people struggling wih this issue.

Attached is the grasshopper definition.

Cheers and good luck,

This is very clever! The only issue I see is that if the input data is not in the form {0;A}(i), the path mappers will have to be modified to achieve the desired remapping. This is a limitation of path mappers in general, I think - if a definition using them is to be reusable, the data structure going in must be known in advance, something which is not always possible. Inspired by yours, I put together another definition that will work with any input path structure, by using the replace branches component and avoiding the use of path mappers.

(A note: The definition seems to perform sluggishly when complex paths are passed through, but I think this is because of the in-line use of Param Viewers, which I have noticed tend to make the drawing of the GH canvas extremely slow when their inputs are complex. This sluggishness goes away immediately when the definition is clustered.)
